Description

Measures PEF (peak expiratory flow). Comes with the ColorZone tape system, which eliminates the need to calculate zones. The enclosed tape simply peels and sticks onto the TruZone PFM, lining up the green zone with the user’s best reading per his or her physician’s instructions. The included daily record is sized to match the numbers on the TruZone PFM. Once a reading is taken, the meter is lined up with the record so that the result can be marked.
